Abstract

A process for recycling of packings containing reactive residues wherein the packings are introduced into a cold zone and cooled until the residues contained therein solidify and are then crushed in the cooled state, the crushed packings are divided into a fraction containing the reactive residues and at least one further fraction, the residue-containing fraction is introduced into a mixing zone into which an agent reactive with the residues is simultaneously introduced, optionally together with a catalyst, the temperature in the mixing zone being held below the softening temperature of the residues and the reactive agent, and the resulting mixture of residue-containing fraction and reactive agent and optionally catalyst is brought to a temperature sufficient for reaction and reacted in a reaction zone.
